This template sets up a manual taxobox, as a right-side infobox table setting out the biological classification (taxonomy) for a group of living things. For guide to automated taxoboxes, see WP:Automated taxobox system/intro.
Although with a choice of over 160 parameters, the implementation is complicated, it is relatively simple to use. Most parameters are optional, so if a particular entry is not relevant for your case, just leave it out. See below section "All parameters" for a complete list.
